Not directly. Fatty acid β-oxidation results in acetyl CoA, which is then entered to the Citric Acid cycle. The "last" step of the cycle is the formation of oxaloacetate from malate.

Can fatty acids and glycerol be used as sources of energy?
Yes. Fatty acids undergo beta oxidation and make acetyl coA, which goes through the TCA cycle until it reaches oxaloacetate. However, a fatty acid cannot be used to make new glucose. Glycerol can enter glycolysis by being converted into glyceraldehyde 3 phosphate.
Before fats can be metabolized in aerobic cellular respiration they must be converted to?
Fatty acids and glycerol.
How is fuel metabolism in the liver changed during prolonged starvation?
Prolonged starvation will stimulate the degradation of proteins in order to produce glucogenic amino acids. The excretion of urea in urine will hence increase to remove the nitrogen waste.These glucogenic amino acids can be converted to oxaloacetate and the oxaloacetate can enter the TCA cycle for energy production. The oxaloacetate can also be converted to PEP for gluconeogensis and the glucose formed can help maintain the level of glucose in the blood.When the oxaloacetate runs out, the lack of its presence prevents acteyl-CoA to enter the TCA cycle. This will lead to the accumulation of acteyl-CoA, favouring the production of ketone bodies. The ketone bodies are then used by the brain as fuel.
Approximately what percentage of triglycerides CANNOT be converted to glucose?
triglycerides consist of 3 fatty acids and glycerol. because fatty acids break down to acetyl CoA they cannot be made into glucose. the glycerol portion of a triglyceride can be converted to pyruvate and thus yield glucose. and glycerol is about 5% of a triglyceride molecule. So the answer is 95% of a triglyceride (fatty acid) cannot be converted to glucose.
How are omega-6 fatty acids taken?
Omega-6 fatty acids may be consumed either as linoleic acid in oils that contain high levels of linoleic acid, or in the converted form, GLA, in dietary supplements.

What is the most common building blocks of lipids?
Fatty acids and glycerol

Distinguish between saturated fatty acids and saturated fatty acids?
There is no difference between saturated fatty acids and saturated fatty acids. If you meant saturated fatty acids and UNsaturated fatty acids, then the unsaturated ones are the ones with double (or, theoretically, triple) bonds in the carbon chain.
What are unsaturated fatty acids?
Unsaturated fatty acids are fatty acids that have double bonds in their long carbon chains.
What molecule is pyruvate initially converted in the anabolism of glucose?
Pyruvate is initially converted to oxaloacetate in the anabolism of glucose. That molecule in turn is converted to phosphoenolpyruvate.
What are components of fats?
Fat is made up of fatty acids and glycerol. A triglyceride is formed when a glycerol forms with three fatty acids.
